Answer 1

The asset can be read using the AssetsManager. Try below code snippet to read file from asset.

Android.Content.Res.AssetFileDescriptor afd = this.Assets.OpenFd("File name");

Updated Answer :

The following code snippet will help to play media file directly from the Asset folder.

Android.Content.Res.AssetFileDescriptor afd = this.Assets.OpenFd(fullPath);
     if  (afd != null )
     {
         player.SetDataSource (afd.FileDescriptor, afd.StartOffset, afd.Length);
         player.Prepare ();
         player.Start ();
     }
